Beyond that, I've been wondering about this. Liz started out telling her class "This week, we are going to imagine what life was like on an ancient sailing ship!" But I'm assuming that she was only referring to learning navigation, because there's not too much else that happened on an ancient sailing ship that would be educational. (Drinking putrid water, hallucinating...and don't even tell them what a mutiny is!) And I'm further assuming that they're not just looking for the North Star; they're also going to draw up a star chart. (But I still don't see why they need a telescope, if they're supposed to be recreating ancient times.)
So has it been a whole week, and the stargazing is the payoff? If it has, then it's plausible that the kids came home every night and described the day's lesson to their parents, so that at this point, they'd know almost as much about it as the kids themselves. (I get the impression that EVERYTHING that happens in Mtig gets hashed over repeatedly. If someone runs over a squirrel in their truck, it's probably big news for days.) But it only looked like one day in the strip, so Lynn must have done one of her time jumps. Don't give any indication that they've done any actual WORK or anything; just focus on the Native quips that make Liz's eyes bug out.
Panel 2: Yeah, that's what I figured: a phone tree. Still having a hard time comprehending that this is a social event. I mean, it's great to be involved in your kids' education, but c'MON.
Panel 3: "Most" of the village? Who's NOT coming, then? And what does she mean, didn't expect it to be a party? Slow learner, this girl, especially since she already caved to the wheedling for refreshments.
Panel 4: ANOTHER bug-eyed look from Liz. And a smug, closed-eye Native look as well. Cripes.
ETA: And something else I wonder about. Is this ALL they're doing this week? No math, no reading, just Celestial Navigation on an Ancient Sailing Ship? I can see how it would fulfill a science requirement, and maybe history if she tied it in with Magellan and Columbus and so forth. But is it customary to devote all classroom time to one project? Quite honestly, it wouldn't surprise me. I do get the impression, from Liz's convo with Gary early on, that teaching in Mtwiggum is a what-the-market-will-bear situation. Plan your lessons around what you can get the kids to pay attention to, rather than insisting that they pay attention to a curriculum that was thought up by Southerners. ETAAgain: All right; I guess I was unfairly snarky. Sorry.
